Abstract

The second recess of the frame body (10) has a first mounting recess (141) provided in the lower part, a second mounting recess (142) provided in the upper part, and a first mounting recess (142) provided in the upper part in a vertical section perpendicular to the annular extending direction. A third mounting recess (143) connecting the mounting recess (141) and the second mounting recess (142). The width of the third mounting recess (143) is wider than the width of the first mounting recess (141) and narrower than the width of the second mounting recess (142). The gasket (20) has, in a vertical cross-section perpendicular to the annular extending direction, a hollow gasket portion having an airtight hollow portion inside, and a solid gasket portion connected to the hollow gasket portion, and is formed with an airtight The hollow part is cut into the cut part (203a) up to the middle part of the solid pad part. The boundary between the second mounting recess (142) and the third mounting recess (143) is in contact with the hollow spacer, and the mounting surface (30a) of the plate (30) is in contact with the hollow spacer.

Description

technical field [0001] The present invention relates to a mounting structure of an electrical equipment casing in which an electrical equipment casing is mounted on a board with a spacer interposed therebetween. Background technique [0002] Conventionally, in a factory, an operation panel in which electrical equipment such as a display is mounted on a panel of an operation panel is used. When there is a gap between the casing and the board of the electrical equipment, liquids such as solvents and oils used in the factory may intrude into the casing through the gap, and dust or the like raised in the factory may pass through the gap. penetrated into the inside of the casing. Therefore, by arranging a sealing material between the frame body and the plate, the inside of the frame body is hermetically sealed. [0003] However, at least one of the frame body and the plate may be deformed due to the reaction force generated in the sealing material when the sealing material is c...
